PLATE-PRINTING MACHINE.

Application filed March 12, 1921.

To all whom t may concern:

Be it known that I, RUDoLPH SATTLER, a citizen of theUnited States, residing at Cincinnati, in the count)7 of Hamilton and State of Ohio, have invented certain new and useful improvements in Plate-Printing Machines, of which the following is a speci` fication.

My invention relates to printing, and more especiall)7 to printing from engraved plates; and the objects of my improvement are to utilize power 'rather than Vhand operation.

thereby allowing a more compact design ofl the machine andincreasing the rapiditj)7 of the wor t, without impairing the quality. Other objects will appear in the course of theV ensuing` description.

l attain these objects b v the device illustrated, for example, in the accompanying drawings, in which- Figure 1 is a frontelevationof a machine embodying inv invention, together with its support and side tables;

Fig. 2 is a sectional plan view of the machine. the section being `on planes corresponding to the brokenl line 2 2 of Fig. 6, the side tables being omitted in this and in subsequent views Fig. 3 is a detail end elevation of the D- roller; i

Fig. 4l is a partial vertical section on a plane corresponding to the line 4-4z of Fig. 2:

F 5 is a side elevation of the machine,

with parts `broken away to reveal certain interior constructions;

. Fig. G is a vertical lengthwise section on planes corresponding to the broken line 6,-.-6 of Fig. 2;

Fig. 7 is a side elevation similar to Fig. 5, but showing a modification of my invention; Fig. S is a side elevation of a machine embodjving another modification of my inA vention: and

Fig. 9 is a plan view of the part of the bed of Fig. 8 adjacent to the far right-hand across between and are lined to the sides 2v 4and 3 near the front end and middle: and at the rear a plate 4l extends across between and is fixed to the tops of the sides 2 and 3. The traveling bed 5 1s mounted between Serial No. 451,678.

the tops of the sides 2 and 3, resting on rollers G near the front end and rollers T and 8 near the rear end. These rollers 6, 7 and 8 are in pairs, rotating on studs fixed in and extending inward from the upper parts of the sides 2 and 3; and the bed 5 has straight lower faces 9 to rest on 4the smooth peripheries of these rollers. Also, there is a middle pressure-roller 10 loosely7 mounted on studs 11 fixed in and extending inward from eccentric bearings 12 rotatable in respective frame sides 2 and 3 and having slotted segments 13 outside thereof, with a clamping screw 14 through each segment slot intol the frame side. These serve to hold the roller 10 at slightly different heights. The roller 10 is reduced in diameter abouty midway of its length; and the bed 5 has opposite straight lower'faces 15 to rest on the smooth peripheries of the respective unreduced parts of the roller 10.

Each frame side 2 or 3 has near the middle of its upper edge a standard 16. These standards have middle openings in which respective bearing blocks 17 are slidable up and down.. each supported b v a spring '18 between its bottom and the bottom of the standard opening, and held down by an adjusting screw 19 passing down through a cap 20 fixed across the top of the opening.V Each screw 19 has a lock-nut 19 with a supporting spring 19 to facilitate adjustment when the nut 19 is loosened. These blocks 17 support the D-roller 21, of segmental shape (Fig. 3) to rotate over the bed 5, hav ing the transverse sha-ft 22 through it and bearing in the blocks 17.

Between theend of the D-roller 21 and `the righthand standard 16 aspur gear 23 is fixed to the roller 2l and its shaft, 22, coaxial therewith. with some of its teeth omitted. The preferred proportion of omit-ted teeth, and the relation thereof to the D-roller. will be described later. A rack 24; is mounted along the right-hand side of the bed 5. to travel therewith, having its teeth upward to mesh with the toothed part of the gear 23 as the bed and rack travel backwardly and as the gear 23 rotates over forwardly. as will be described.

This rack 24: is so mounted on the hed 5 that it can slidelengthwise of the bed, being held for this bv screws in lengthwise slots of the racl: and fixed in the side of the hed. The front end part of the rack is reduced, leaving a shoulder. and the bed has a slot up and down through it, across which this reduced part extends, with a spring 26 coiled around the reduced part with its rear end against the rack shoulder and its front end against the front end ol the Vbed slot. Thus, with the screws loose, and not clampingthe rack 2l to the bed, but onlj.r guiding it, the rack 2li can yield forwardly lengthnise of' itself and ot the bed. lts torn'ard and rearward movements are then limited. by engagement of its rear endv and its front shoulder, respectively, u'ith shoulders onk the bed 5 at opposite ends ot' thev rack gruidewajv (Figc: (l). A lguard 23. fixed to the standard 16, covers the gear 2?); and a lguard 2li. fixed to the trame side. 3, Covers the rack 24r- When the latter is in its forward position with the bed The screws'l can hetighteued utter the first meshing of' the rack 2l and gear 23, 'with' Whatever yielding the rack may have hadgin adjusting` itselt to the Lrear Q3 due to anyv ,inaccuracy in the. relation of the D-roller back-ing to the bed liloneif'er, in practice, I find that this rack mayr be lett :tree to yield' at each reciprocation of the bed adjustine to compensate for inaccuraejT each time. though these inaccuracies may varyY` from time to time: all ot which will be more fully described later. i

"tf the opposite side ot the machine the D-roll-er shat't Q9 e \:tends out past the bearing block i7; and on this extension a spurgrear 2 isclamped hv its hub Q8` to mesh with a similar spuugear Q9 turning ou a stud exteiiding' out from the liraineiside Q .directly below the lrear 2T. To the rear. a spur-gear 30, of twice the diameter ot the `rear 27. `turns on a similarly1 mounted stud some distance lower down, and this larger kgearmeshes With'the intermediate lear 29. All'of these gears 2T. QQand 30 have complete sets of teeth; and, as gears. they simply makeup a trainto reach 'from 'the'D-roller down to a lower mechanismof the imiehine` presently to' be described. The. lear il() .is madetnice :is large as the others to reach thisV distance'without use ot' a greater number of gears; it not being' necessarily larger for the purpose ol the'working ot the additional details now to be desaib'ed; but it is sutlicient to say that in any rariatitm., with such. a gear.y it must be of the same diameter,

or else al diameter that is an eren multiple of the diameter o'l the D-roller gear QT. I

This large gem-150 has an outwardly extended larg-e hub 3l, on the .tace otWh ich is fixed the locking yoke 3Q. diaimtricallj tliereacross` with concave ends. Ailse. close to 'the respective ends ol this yoke, against opposite sides oi the hub 31, are lgeant-sectors 32%, :fixed to the gear 30. Each sector 33 has 'tom' teeth, onljv two ol which rome into use as Will later be described. the ercess :number being; to permit ol adjustim-nts. lt will be understood thatfthe number of sets otthese conca-re elements and these sectors will equal the ralue oit the ratio of: diameter ot the gear 30 to that of the gear 2T. Were `1t lthree times the diameter or the gear 2 there would be three sets, and so on; or it the saine arrangement or the len gthot gea r train used.

The main shaft 3% is jonrnaled transversely in bearings -zllfand 23st in a casing l5-on the basel near the leiftside at the rear; and has an extension out 'past the side 2 With a rotor 3G fixed on it, comprising a braltewlrum 37, a hub 38, and, outermost, a flange 39, A cover or euard -lO is .fixed to the side il over the geai i f1 Q9 and 30 and this rotor 36.

Inside the casing' the shaft is enlarged, forming the Yclutch member tl next to the outer bearing`v and has a gear member comprising the gear steps 4t2 and #13, rotatably mounted on it next-,to the inner end of this member` el, with its adjacent side dished to receive` this member 4l. Across the tace ol this member' 4:1 is a deep key-Way dll;v and in the adjacent tace ot the gear member, to register withv the adjacent end of' the lrey-nfajf-ll1l, area number or radial slots- 45, there beine' as herein shown (Fig. '6.)

The niorin-g'carll is directly on the main shaft 34;@ in: this example, andthe Worin 9i extends foiwvardly, with a gear 111 lined thereon. These gears and the ivorm are infninted in the pedestal 35 mounted on the The motor 92, on the base l, has its shalt coupled to the driving;- Shatt'112 having a bearing fixed on. the base l and haiiing ixed on it at opposite ends ot the bearing 113 the gears 111 and 115 ol dillerent diameters. Above these, the lay-shatt 116 is journaled in a yoke 11i'7 slidalile parallel to the shaft` 112vvhich is alined with the niotor shaft and-:Witlrthe Worin shaft. A brac-het 11Ssupports the yoke 11T for this movement, and gears 119 and lf2() are fixed onfthe shat't 116 at opposite endso'lthis yoke, to niesh with 'the t(rear 114 or the gear l'liespectiveljif, as the yoke is shifted by a levcr121 tulcrunied on the casing` 122 that eneloses thegears.- The" shifter-rod is Connected to the lever 121 and exten(ls-forward to a suitable Stop plate 122-1 and has ahandle 125 outside lthe trout otf the inachine. The layshatt 116 also Vhas fixed on it the `-(gear 126 meshing With the Worin-shalt gear 111, Wlnchis'vv'ide enough to Areceive the gear 1:26 ininesh in any otl its positions.

It will be understood. that thev clutch is substantially the saine as 'in therstexample, l

The extension driven and controlledijhas fixed enit the spur-gear- ?)Gfg and idler gears 37 and 38l operatively connect this gear awvith the gear Q-i' on the D-roller shalt these idler gears being loosel;T mounted on respective studs 39? tired in and extending out lfrom the frame side ,The gears 2T and SGLare of the saniediaineter; `and preferablythe ,idler gears are` also of this diameter. .The gears are covered by a guard 11W.

Neart-he fronton? the niaehine'aresilient plate curved upwardly 'troni' and lined to the traine side 2 torins a brake 12T, With leather a. volute spring 131 fixed to its inner ni ll' land to ausha'lt 132 on which the easing 130 turns; the shat't being-` lined tothe sides 9b.

Thus this spring` 131, .inap'ain uinvinding, pulls the bed forward again after anop ol the -inain shaft 31% thus` eration. The machine is provided with the stop-plate 91 and associated details, as in the previous examples; and it also has the forward brake 127, as in Fig. 7.

The D-roller 21b of this machine, like the D-roller 21L of Fig. 7 is of somewhat greater angular extent than that of Figs. 1 to 6, inclusive; and these D-rollers have spring clips 77-l or 77 b for the clamp bars 7 5a or 751 instead of clamping screws and plates as in the first example. Any of these maybe interchanged, and it is understood that the angular extent of the D-roller is subject to variation according to design; and like other dimensions of parts is a mattei' of degree. The gear 133 fixed concentric with the D- roller 21", in Fig. 8, however, is complete, and does not mesh with the bed rack, but with a gear 134 of the same diameter fixed on the shaft 11b with the pressure-roller 10"; and this gear 134 meshes with another gear of the same diameter, fixed on the shaft 136. The shafts 11b and 136 are journaled in the frame sides 2b, and thel gears 133, and 135 are all at the right-hand or far side of the machine. At the near side, a .larger gear 137 is rotatably mounted on the shaft 136 and has a clutch member 138. Another `clutch member 139 is fixed on the shaft 136,

and a suitable clutch-bolt 140 is springpressed to enter slots 139in the member 138, from the member 139, when released by withdrawal ofthe clutch-finger 141 by depression of the starting-lever 142. The resetting leverV 143 is also fixed to swing with the. lever 142 and finger 141, and bears on the face of the cam 144 fixed on the shaft- 136 and having' an abrupt drop 144 and increasing in radius from the inner end of this drop around tothe outer end thereof.

The gear 137 meshes with lapinion 145 fixed onv a transverse` shaft 146 along with a large gear 147, this shaft being journaled in the frame sides 2. The motor 14S, on the base 1b, has' a pinion meshing with the gear 147.

A. safety pawl 149 is pressed forward against a pin 150 in the end of the D-roller 21", by a tension spring 151 connected to the standard 16'). In this example, the D- roller is driven directly, and it is the bed 5 that is indirectly driven. A cam 152, fixed on the D-roller shaft 22b between the gear in the rear of the right-hand standard 16", against a spring 159, to cushion the return of the bed forwardly under the action of the spring 131 and with the .help of the brake 127, stopping the. bed with the nose.

of the bar 155 very close to the concavity of the cam 152 as shown. The-rack 24b is mounted on the right-haut or far side of the bed 5 by means of screws 25h extending through lengthwise slots therein into the bed 5, as in the previous examples. Here, however, the spring arrangement is the reverse; allowing the rack to yield backwardly. The rack thus has a slot 160 with a lug 161 of the bed 5 extending out through the rear end, and having a lug 162 on the rack at its front end, witha spring 163 compressed between the rack vlug and a` screw 164 in the lug 161 of the bed. The screw may be used to adjust the pressure of the spring 163; this being also applicable to the other examples, for adjusting the pressure of their spring 26. The teeth of the rack 24b face downwardly, and a spur-gear 165 is fixed on the pressureroller shaft 11b, between the gear 134 and the pressure-roller 10b, in the` path of the rack` 24". The teeth of this gear 165 are omitted throughout a considerable segment, which is uppermost at the starting position as shown. The heater mounting in Figs. 7 and 8 comprises a plate S3 fixed across the front of the frame, with a vertical guide-slot 84, on which the bracket 85a is clamped at any suitable height, by a clamp-screw through the. slot S4, thus support-ing the lamp 86 at the required height as in the first example.

1n respect of certain specific differences from the example of Figs. 1 to 6, inclusive, 'the example of Fig. 7 is claimed in my co- Apending application, Serial No. 401,192, filed August 4, 1920, and the example of Fig. 8 is claimed in my copending application, Serial No. 388,889, filed June 14, 41920.

Operation: In any example, suitable backing is clamped around the` D-roller by means of its clamping bars. The engraved plate A is laid on the bed 5, withits engraved side up, and the plate 91 is adjusted forward or back so as to hold the plate A in the right printing position on the bed; which will generally be such as will bring the plate about symmetrically under the working face of the D-roller upon impression. rlfhe plate A beinginked and wiped as usual., the stock is laid on the plate A withoutany positive stop to gauge the position thereof; this being` effected, as is customary in plate printing, merely by drawing a line on the plate A, to mark the position of the edge of the stock. This is done with `the bed 5 in its stationary forwardmost position vas shown in the drawings. The motor 92 or tion or during this period, is compensated by the slight yielding of the rack 24 forwardly; that is, the rack allows the D-roller to adjust the bed backward to itself, under the pressure. `But the spring 26 is strong enough to cause the D-roller to be driven by the bed, after suchcompensation has been established, positively, and not by hand operation.

frictional transmission as in other machines, such as the well-known hand-operated plate printing machine, which, under the `rapid action -of power driving, *would blur or smudge the work by. the slippage of the bed relatively to the D-roller. The compensation effected by the spring mounting of the rack that limits slippage of the bed and D- ro-ller relatively to eachother is so slight as not to be appreciable during the impression stage. Thus, lack of skill in providing the D-roller backing, or wear or other` inaccuracy in the machine parts, will not have any noticeable effect in the work, with the yielding or fioating rack as set forth. rlhis also provides for slight variation in thick-` ness of plates `A or of the stock; theoretically it being required that the top of the stock be coincident with the pitch line of Vthe rack 24.

Ordinarily, in ka' plate printing-machine, the plate A is merely ylaid on the bed, or is secured withlsome light adhesive, for Under power operation,` however, the forces tend to-shift the plate thus insecurely ;mounted. The stop-plate 91 affords alp'ositive positioning means forv vthe plate A, resisting forward slipping as the bed drives 'back against the D-roller, especially in the compensating action of the floating-rack construction as just described. This plate 91 may be adjusted throughout its front to rear width; or a wider or narrower plate may be Vsubstituted for extreme `adjustments. The disksQ() are past the. D-roller backing edges. f f

The pressure-roller 10 reinforces the bed` 5 as the work passes under the D-roller; and the bed is preferably lthickened to present a bearing surface throughout its throughout the printing length, with the parts Y9 and 15 merging into this thickened part (Fig. 2.) The adjustment of the roller 10 by its bearing segment 13 allows for wear of these parts, so `that complete reinforcement of the bed can always be insured. The provision of the intermediate gear 29, directly below lthe gear 27, in the D-roller initially-driving gear train, permits free up and down adjustment of the D-roller in the standards 16. without interference with the meshing of the gears; it being understood width that these up and down adjustments are slight, proportionate to the gear-tooth depth. The change-speed transmission from the .motor to the main shaft permits the machine to be operated at more correct speeds for various kinds of work, under different pressures as the D-roller is adjusted up or down, or with plates A of greater or less engraved area, or due to a combination of these conditions.` The fly-wheel 93 affords the momentum desirable to overcome slight shocks in starting and during operation due to lack of balance of the operating parts, as the crank 68 and the clutch parts andthe parts on the rotor 3G. Due to the nature of the work, with the stock held in correc't printing position merely by its friction on the plate A, all shocks and jars in'any part of the machine must be minimized. as these are transmitted to the bed 5 and `the plate and .stock thereon, and may disturb the stock position. These provisions all cooperate to this end.

In F ig. 7, with the beginning of main shaft rotation and bed travel as in Figs. 1 to 6, inclusive, the gear 2T is rotated on the D-roller shaft by the gear train 37. 38', over forwardly. The turning-pin 30 rotates the D-roller 21nand its mutilated gear 2? forwardly and downwardly to meet the bed 5 and rack 24 at a time when theD-roller and bed surface speeds are approximately equal, as are also the gear and rack tooth speeds. The springs 32a now yield to compensate for the differences between the variable crankeffected motion ofthe bed 5 and rack 241 and the uniform motion of the gear 27 as derived through the train from the main shaft 34a; either the forward or the rearward spring 32"L yielding, accordingly as the former motion is slower or faster than the latter motion. The floating rack 2li will compensate for discrepancies in this exan'ij'ile.v as describedv for the first example; and the brake 12T- andstop-plate 91 will' contribute to the operation as in the other case.. Themodiied change-speed transmission will have the same advantages herein as in the case just. described, as will also the pressure-roller adjustment.

In this case, there is no disconnection of the D-roller 'from the main shaft 34a; but merely the yielding thereof. Thus the upward reari'vard rotation of the D-roller begins the bed 5 reaches its `rearmost position. and is completed as the bed rapidly returns forwardly; the `clutch mechanism automatically stopping all of these parts. with the aid of the brake 12T. after one complete revolution of the main shaft 34, leaving 'the parts ready for the next operation.

`In F 8 and i, depression of the starting-lever l-il2 actuates the clutch with the same effect. substantially. as in the clutch of the otherfexamples. Then the concave part ot thefcaiu 152 engages the nose ot the .bar 155, starting' the bed 5 bacltwardlyv Very slowly, and gradually increasing;` thespeed of the bed` until, when the iiist tooth o the gear 165,` at the front ot its Vacant space, engages ytli-.e oncoming' rack tooth, these parts are traveling' at substantially the saine speed. Then the travel ot the bed 5 is constant, as driven by the rear 165 meshing with the raclrl, until the vacant part o" the rear .165i comes around to the rack, atteran almost complete revolution of the t(rearA 165 and the clutch. The latter then automatically acts, by its cani istat and the bar letti, to disconnect `and stop the meclianism, aiter the D-roller has made exactly yone revolution, so that when the springl 131 now returns the bed 5 forwardly, all parts will again be in initial or stocloreceiying;l position, tor the nekt ope "ation, In this, as in the preceding' examples, the iicating rack 2st, yielding' backiwirdly, `will have the same advantages as to compensation 'i'o'r inaccuracies in the mechanism ortho D-roller laickinp,v or height ot steelt` surivgv vze; and

the brake 127 and stop-plate 91 wil function substantially as in the other examples.

vThe absence o'l" hand labor oi turning,` the -roller 'very steadily and carefully, and as `c aret'ully advancing the bed thereunder with the work, as in the ordinary hand press, adapts my intention especially for more rapid `work with. less manual labor. rhc wmpactness permitted by the power cperation, permits a more convenient installation otl the machine, as with the closely accessible'worl: tables at both sides, as in Fig.

'1` `which' will heiuiderstood to be equally Aapplicable to the examples et Fig. 7 and Fig, 8, either as in Fig'. 1 cr in a modified ifo'rm, as 'tor instance those shown inthe corresponding' co-i'iending applications bet'orc referred to. T he result of my inven tion theretore is to increase the quantity and quality of the output.

Other modifications may 'occur in adapting the invention to various uses, or under di'ierent conditions, or as matters ot preterleure, and therefore, while certain constructional details are deemed preterable in con-` nection with my invention, and l have shown and described these rather specifically' in elucidatingr the construction and use of my `inrentitm, as is required, l do not wish to be understood as being limited to such prelcise showing` and description, but haring' thus iully describetl .my invention, `what I claim as ncwand desire to secure byLetters Patent is: I
